Question
For the consecutive first-order reactions: $A\overset{\quad K_{1}\quad}{\rightarrow}B\overset{\quad K_{2}\quad}{\rightarrow}C$, in what condition, $\lbrack C\rbrack = \left\lbrack A_{0} \right\rbrack.\left( 1 - e^{- K_{1}t} \right)$?
Options
A.K1 < K2
B.K1 <<K2
C.K2 < K1
D.K2 << K1
Solution
On derivation $\lbrack C\rbrack = \left\lbrack A_{0} \right\rbrack\left\lbrack 1 - \frac{K_{2}.e^{- K_{1}t} - K_{1}.e^{- K_{2}t}}{K_{2} - K_{1}} \right\rbrack\ \left( \text{when }K_{1} \neq K_{2} \right)$
If K1 << K2, [C] becomes $\left\lbrack A_{0} \right\rbrack.\left( 1 - e^{- K_{1}t} \right)$
